Application March 7, 1932. Serial No. 597,105 4 Claims. (01. 219-3837) Figure 2 is a sectional plan View of the samef Fig. 3 is a perspective view of one of the steam chambers, and. Fig. 4 is a perspective view of one of the air tubes with its lower end held uppermost to show the screw holes through which screws extend to fasten it to one of the steam chambers. r

Throughout the various views of the drawing, similar reference characters designate similar parts.

My improved radiator 1 may be mounted on a base 2 which, in the present embodiment, is alsomounted on casters 3, although it may be mounted in any suitable manner, and this base is provided with an electric heater 4, which, at its outflow end, has a vertically disposed pipe 5 which is connected to the steam chambers 6 and '7 by suitable fittings. These chambers are composed of a series of castings 8 with top and bottom flanges 9, and internal chambers 10 through which the steam passes. These chambers surround the flanges 9, and to these flanges.

are secured the tubes 11, which form air flues for the passage of air, which is heated by steam 7 such be desired.

The tubes 11 are sheet metal and preferably made of copper, and are provided with holes 16 (shown, in Fig. 4) through which screws are passed in the corresponding holes 17 in the flanges 9.

In View of the foregoing, the operation of my radiator will be readily understood. I

Let it be assumed that sufficient water is in the apparatus, and that a power is turned on to the heater 4. Under such circumstances, water in the heater will be expanded and may be converted into steam according-to the temperature of the heater, but whether steam or water, the heated product passes upwardly through the pipe 5 into the steam chambers 6 and 7, whence it passes as above described. After heating the fiues 11, air rising through these flues is also heated whereby the water is condensed or cooled and returns to be re-heated.

While I have shown and described one embodiment of my invention, it is obvious that it is not restrictedthereto, but that it is broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is: I

1. A radiator having a water-receiving chamber, an electric heater disposed in said chamber for heating the water contents, pipes extending from the opposite ends of the water chamber, spaced groups of connected steam boxes extend ing between and joining the pipes, each of the steam boxes having a central passage extending through it, .the passage being open at both of its ends, the opposite ends of said .passage terminating in flanges extending from the box and pipes connecting one flange of each box in one group with a flange on each box in the other group. I

2. In a radiator, a hollow steam box having entrance and exit openings for steam, a central passage extending through the box and open at both of its ends but closed to the interior of the box, the ends of said passage terminating in flanges which project beyond the ends of the box, and pipes fitted over the flanges and projecting therefrom.

3. A radiator composed of, several groups of steam boxes, the boxes in each groupbeing consteam boxes and a lower group spaced from the upper group, each box in each group being formed with a steam chamber and an air passage closed to said chamber, the steam chambers in the steam boxes in one group being in communication with those in the other group only at the ends of the groups, air pipes extending between. and connecting the boxes of the two groups, and air pipes fitted to and extending above the tops of the boxes in the upper group.
